Title: Method for upward flow sludge blanket and device therefor
Inventor: TOMITA MINORU
IPC: C02F3/08
Filed: 1991-11-06
Abstract: PURPOSE:To achieve enhancement of treatment efficiency, prevention of consolidation and blocking and operation of high load and to promote granulation of sludge by drawing out one part of liquid from a region wherein water is transferred to a liquid-gas separation zone of the upper part of a blanket zone from this blanket zone and returning the same to a drainage feed route. CONSTITUTION:A bubble separation block 8 having the cross section of a triangular shape is oppositely arranged in the aperture of the lower end of an oblique partition 7. A circulation pipeline 13 which is opened in one end and connected to the supply pipe 3 of untreated water in the other end is provided in the lower side of the bubble separation block 8. Water is returned through this circulation pipeline 13 by a circulation pump 14 provided on the way. By this constitution, untreated water is supplied to a reaction tank 1 at flow speed suitable for glanulation of granules by returning water passed through a sludge blanket zone to the supply system. Moreover, water is allowed to upward flow at comparatively slow flow speed suitable for liquid-gas separation in a liquid- gas separation zone because influence based on circulation of this water is practically unaffected in the liquid-gas separation zone.

Filed: 1988-11-18
Abstract: PURPOSE:To shift the corner point of a route at a high speed and with high accuracy by reducing the shift speed down to an allowed level toward the corner point and increasing the shift speed up to an instructed level after the corner point. CONSTITUTION:An input part 20 inputs simultaneously the data on rectilinear segment A which starts its shift, the shift speed, and the data on the next segment B. A corner angle calculation part 21 calculates an angle theta formed between both segments A and B, and a corner speed calculation part 22 calculates an allowed speed Vc for the shift at a corner point Q. An acceleration/deceleration processing part 23 gives the acceleration/deceleration processing to the command speed Vi outputted from a speed command production part 2 with use of the speed Vc so as to satisfy this speed Vc at the point Q. Thus an output speed vi is obtained for each sampling period. The speed vi is integrated 4 to obtain a shift distance Li. Then the shift ratio is calculated 6 from the ratio between the distance Li and the segment length La. The X and Y axis servo circuits 8a and 8b drive the X and Y axis servo motors 9a and 9b respectively based on the output obtained at an interpolation arithmetic part 7. At the same time, a segment termination discrimination part 5 discriminates the segment termination.

Abstract: PURPOSE:To prevent delay in access by using a cache comparator so as to compare the content of a tag memory with a high-order address when a low- order address is inputted and giving a refresh signal by a timer clock when the coincidence period continues for a prescribed period or over. CONSTITUTION:A cache memory 13 uses a cache comparator 15 to compare the contents of a tag memory 14 receiving a low-order address at a part of an address from a CPU 10 with the high-order address and a coincidence signal is outputted for high speed operation. A refresh signal is raised a the leading of the cache access signal and when the cache access signal has a prescribed time or over of interval, a refresh signal is caused by the refresh request signal by a timer clock. In this case, since no access is given to a DRAM 11 being the main memory, the refresh signal and the signal accessing the main memory 11 from the CPU 10 do not collide with each other. Thus, the retarded access is prevented.

IPC: H01J31/12
Filed: 1988-11-17
Abstract: PURPOSE:To construct an image display device thin and obtain a high brightness by constituting an electron beam trimming means at least partially as an electron boosting means. CONSTITUTION:An electron beam emitted by heating a linear hot cathode 8 and adjusting the potentials of a vertical scanning electrode 7, cathode 8, and control deflecting electrode 9 is deflected in the x direction and reaches an aperture in a channel plate type electron booster CP10, where the first beam trimming is performed. This boosting of electrons by CP10 requires lesser amount of electron beams from the cathode 8, so that burden on it is light, which prolongs its lifetime. Then the electron beam is converged at a convergence electrode 13, deflected in the x direction to a certain degree by an aux. deflection electrode 11, runs against an anode 12, and emits light. Vertical scanning is made while the electron emission from the cathode 8 is controlled by the electrode 7 in the sequence from the top of the screen downward. Because modulation of image signal is made prior to the CP10 in the low region of electron energy, which therefore can be managed with minor amount of power consumption. As a supporting member 5 is covered with a high resistance material, there is no risk of electric charge due to collision of electrons, etc. This enables constructing the device thin and equipping it with high brightness.

Filed: 1990-10-31
Abstract: PURPOSE:To reduce a mask process by a method wherein the metal surface of a drain electrode and a drain bus is oxidized anodically and an oxide film, of a dense structure, which has been formed on the surface of a metal layer is used as a mask in order to remove the metal layer at a display electrode part. CONSTITUTION:By utilizing a terminal at the peripheral edge part of a liquid- crystal display element substrate, a drain electrode 24a and a drain bus are oxidized anodically. At this time, the drain electrode 24a and an Al layer 24b are connected via a semiconductor active layer 16, but they are in reality in an insulated state because the semiconductor active layer 16 formed of undoped amorphous silicon is at a high resistance. As a result, an anodic oxidation film 26 is formed only on the surface of the drain electrode 24a and the drain bus. When this assembly is immersed, e.g. in a phosphoric acid-based etchant, only the Al layer 24b is etched, and an ITO film 22b to be used as a display electrode is revealed. At this time, the anodic oxidation film 26 of a dense structure functions as a mask; the drain electrode 24a and the drain bus are not etched.
